The failure or degradation of solar absorber tubes is the single largest cost factor for current parabolic trough solar power plant. The main failure reason is that there are residual stresses in the glass-to-metal joint which are generated during the cooling process of sealing. According to the...

The breakage of the glass to metal sealing is the primary ongoing issue for the solar receiver tubes in parabolic trough solar power systems. Sealing failure leads to loss of the vacuum inside the tube which substantially reduces the collector efficiency. It is a technical difficulty to obtain...

Here the experimental technique for measuring the thermal conductivity of nanofluids at the temperatures above 100 °C has been developed, and a systematic research on the thermodynamic properties including thermal conductivity, viscosity, specific heat and density, of the graphene-dispersed...
